Someone at macserialjunkie board posted a problem with the mpress packer. Since packers are a pretty rare thing at OS X and I was bored, I decided to give it a quick look. The result is another tutorial about manually unpacking this kind of binary. It’s not hard and the packer isn’t that great.

Objective-C binaries can be dumped but there is a problem with NIB references, I think. I was already investigating this problem with other dumping experiences. Some other stuff must be fixed before Objective-C binaries dumps can be used. If you have any hint about this, please do tell me!

If something isn’t clear or it’s missing, feel free to leave a comment so everyone can enjoy it.

That’s it for now! Enjoy!
